A recent study indicates that patients who come off blockbuster weight-loss injections like Mounjaro or Wegovy can put back on lost weight at a significantly accelerated pace than those who halt traditional diet and exercise programs.
Research printed in a leading health publication demonstrates that while obese individuals often shed a large proportion of their total mass while using the jabs, the weight returns at an average rate of nearly a kilo each month upon discontinuation.
"People buying such drugs need to be informed of the danger of rapid weight regain when the therapy is stopped," warns lead investigator Dr. Susan Jebb.
Such speed of recovery implies a return to original weight in about 18 months.
Weighing Therapies
The research, which looked at 37 of studies involving over 9,000 of patients, contrasted the effects of these new drugs with conventional dieting.
Scientists note that individuals who lose weight through dieting generally experience a slower creep back—perhaps 100 grams monthly—after stopping.
Explaining the Rapid Regain
Nutrition scientists propose the way of the drugs explains the heightened regain.
The injections copy a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Long-term administration of the hormone concentrations several times higher than normal may cause the system to produce less of its own natural GLP-1, and could diminish sensitivity to its effects," said Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this GLP-1 'fix' means appetite is uncontrolled, making excessive eating far more likely."
A Chronic Disease?
The NHS advise the jabs for individuals with weight-linked health risks, alongside prescribed lifestyle changes.
Many experts say that, considering the high risk of weight regain, the therapy is often ongoing.
This view is supported by drug manufacturers, who state that the findings "highlight the persistent nature of obesity," akin to managing diseases like high blood pressure.
Patient Experiences
Individuals who have stopped the medication report a sudden resurgence of hunger.
"It felt as if a switch activating and you're instantly ravenous," recalled one woman.
This difficulty is exacerbated if patients have not adopted sustainable lifestyle or habit changes during treatment.
Growing Interest
Survey data indicate that millions of adults in the UK have tried these injections in the last 12 months, with desire continuing to grow.
- Use is higher among females than men.
- The middle-aged demographic shows the highest usage rates.
- A large proportion obtain the drugs through private prescriptions rather than the NHS.
In conclusion, experts stress that while these medications are potent tools for weight loss, they are not a magic cure and lasting health benefits relies on combined lifestyle management.
